Runner Pool

Proposes replacing Terragrunt's group-based execution with a dynamic runner pool that schedules Units as soon as dependencies are resolved. This improves efficiency, reduces bottlenecks, and limits the impact of individual failures.

runner-pool - What it does

Allow usage of experimental runner pool implementation for units execution.

runner-pool - How to provide feedback

Provide your feedback on the Runner Pool.

runner-pool - Criteria for stabilization

To transition the runner-pool feature to a stable release, the following must be addressed:

• Use new discovery and queue packages to discover units.
• Add support for including/excluding external units in the discovery process.
• Add runner pool implementation to execute discovered units.
• Add integration tests to track that the runner pool works in the same way as the current implementation.
• Add performance tests to track that the runner pool implementation is faster than the current implementation.
• Add support for fail fast behavior in the runner pool.
• Improve the UI to queue to apply.
• Add OpenTelemetry support to the runner pool.
